Here's a system that I used for saving work offsets when I still used SB3. It utilized the Buttons add on in the Tools menu (or could also be set up to use in the custom cuts menu). It's been quite some time since I've looked at it, but all the files are here, and I think there's some info on using it in the X Y zeroing fixture zip as well. Play around with it and see if you can get it to work for you. You can add more offsets to it if needed.
